Patented Nov. 26, 1929 UiT E ST TES PATENT OFFECE \VILLIAM JOHN BLAKE, OF BUFFALO, NEW YORK Application filed September 9, 1927, Serial My invention relates to improvements in devices for swinging double hung windows and the object of the invention is to construct set of attachments for sliding windows of the standard type which will enable such windows to be swung inwardly for cleaning,

repairing, hanging in place screens, etc. A

further object of the invention is to so con struct my attachments that they can be read ily attached to any standard sliding type of window with the minimum of expense, time and trouble, and another object of my invention is to so position the attachments that they will in no way interfere with the normal sliding function of the window sashes.

My invention consists of a window structure constructed and arranged all as hereinafter more particularly described and illnstrated in the accompanying drawings in which F'gure 1 is a front elevational view of a sliding window showing my attachments for ermitt-ing the sashes to swing inwardly secured in place thereon.

Figure 2 is vertical sectional view taken through the line 22 Figure 1.

Figure 3 is a plan sectional view taken through the line 38 Figure 1, both in window frames being in the lower-most position and swung inwardly.

Figure 4 is an enlarged fragmentary view of the upper corner of one of the window frames showing the sash'weight line detachably secured thereto.

Figure 5 is a further enlarged perspective view of a portion of the left hand upright member, of the window frame showing the hinge connections between the sashes and the frame, and about which the sashes are swung inwardly.

Figure 6 is an enlarged perspective view of a fragn'ientary portion of the upper sash, showing one of the upper sash male hinge connections, and

Figure 7 is a front elevational view of a V shaped catch provided upon the window frame in the vicinity of the sash weight line pulley for re eiving and gripping the line when it is removed from the sash.

Like characters of reference indicate corresponding parts in the different views.

As the object of the invention is to so mount the sashes that they may be swung inwardly it is necessary to slightly alter the window frame in order to permit this swinging movement, and to attain this end the inside stop 1 upon the right hand side of the window frame is diagonally cut at the point 2 intermediately of its height and the lower portion 3 thereof made to constitute a removable member. This member is of course normally positioned in place when it is not required to swing the windows inwardly and held by a plurality of thumb screws 4 which freely pass through orifices 5 therein, the inner ends entering suitably threaded orifices in plates 6 recessed in the window frame.

The thumb screws 4 engaging the plates 6 retain the member 3 or the lower portion of the inner stop 1 in its normal position, and when it is desired to remove it to swing the window inwardly it is only necessary to unscrew the thumb screws out of engagement with the plates. The removal of the member 3 will of course permit the lower sash to be swung but as the upper sash would be held by the parting stop 7 I have out such parting stop in the vicinity of the height of the cut 2 so that the lower portion thereof also constitutes a removable member.

The lower sash 7 is furnished upon its inner face at its upper and lower left hand corners with a pair of swingable male hinge members which each comprise an arm 8 swingably mounted'at its lower end upon a screw 9, which is inserted into the sash and each provided upon its upper end with a curved member 10, having a slot 11 therein through which a stop screw 12 is inserted into the sash, the curvature of the slot 11 of course follows the curve of the circle having its center at the center of the screw 9 which permits the hinge member to swing, its movement being limited by the screw 12 in the slot. Upon the inner and upper end of each of the arms 8 a downwardly extending hinge pin 13 is furnished, being secured by a portion '14 integrally formed with the arm 8 and adapted to tightly encircle the top ofthe hinge pin 13. The portion 14 is bent inwardly from the plane of the arm 8 so that a space is constituted between the hinge pin and the face of the sash to permit the entering of the hinge pin into its respective female member.

The female hinge members each comprise a plate 15 having upper and lower orifices adapted to receive suitable screws for securing them in place, and provided intermediately of their height upon their outer faces with lugs 16, having vertical orifices 17 therein of slightly larger diameter than the hinge pins 13 in order to permit such hinge pins freely entering thereinto. These female hinge members are four in number, two being placed upon the inner left hand stop of the window frame, one being in the vicinity of its lower end and the other intermediately of its height above the top of the sash 7. The outer pair of female hinge members are secured to the face of the parting stop directly behind the members upon the inner stop as clearly illustrated in Figure 2.

Upon the upper and lower left hand corners of the inner face of the upper sash 18 I provide a second pair of male hinge members, these hinge members are rigidly secured to the sash and each comprise a plate 19 having a plurality of orifices therein, adapted to receive screws for securing such plates to the sash, and furnished upon their inner ends with hinge pins 20 which are secured thereto by means of integrally formed portions 21 upon the inner ends of the plates which tightly encircle the upper ends of the pins. These portions 21 are also bent to a slight degree inorder to space the hinge pins away from the sash to permit them to enter the respective female hinge members 16.

The sh weight cords 22 upon the right hand side of the frames from which the sashes are adapted to swing away of course have to be detached in order to permit the sashes to freely swing and to facilitate easy access to the out side of the glass for cleaning purposes, and to attain this end, in each of the sashes I furnish the usual downwardly extending cord receiving groove 23 terminating in an enlarged open recess 24 which receives the knotted end 25 of the sash weight cord. When the sashes are swung inwardly so that the groove 23 is exposed it is only necessary to pull the cord therefrom, when the knot 25 upon its lower end will come out of the recess 2 1. In order to prevent the sash weight from pulling the cord downwardly to its full length within the window frame, I furnish a pair of cord engaging members in the vicinity of each of the sash cord, pulleys upon the right hand side of the window. These cord engaging plates each comprise a V shaped member 26 which is secured by means of suitably positioned screws 27 over the respective sash cord pulleys, the inner lips 28 thereof being curved inwardly to a slight degree so that the sash weight cord when extending downwardly to the sash in the normal manner does not come into contact with the plate but when the cord is pulled inwardly when the sashes are swung it enters the apex of the V and is held against rotation upon the pulley.

The operation of my device is as follows When the window is in the normal position with the sashes slidably mounted, the swingable hinge members upon the lower sash are in the position as illustrated in Figures 1 and 5 and the lower portion 3 of the inner stop is secured in place by means of the thumb screws 1, and the lower portion of the parting stop 7 is of course also in place which will permit the upper and lower sashes to slide in the usual fashion.

When it is desired to swing the sashes inwardly for cleaning or any other purpose the lower sash 7 is pushed upwardly until the swingable male members are above their repective female members after which they are swung inwardly to the position illustrated in dotted lines in Figure 1. The lower sash is then pushed downwardly so that the respective hinge pins 13 upon the swingable members enter the orifices 17 in their respective female members, the swingable members and their female members of course being equidistantly spaced apart. The thumb screws 4 are next unscrewed from the plates 6 which will permit the lower portion 3 of the inner stop to be removed. When this is done it is of course possible to swing the lower sash 7 inwardly about the hinge connections between the swingable male hinge members and the female hinge members into the position illustrated in Figure 3, the sash cord 22 of course being removed from the sash and held in place through its engagement with the V plate in the pulley as heretofore described.

The upper sash is next pushed downwardly so that the hinge pins 20 of the respective upper and lower male hinge members enter the orifices 17 of the respective upper and lower female hinge members 16 upon the parting stop thus forming a hinge connection between the stop and the upper sash, the upper sash of course being in the vicinity of the lower part of the frame as shown in dotted lines in Figure 2. When this is done the lower removable portion of the parting stop 7 is removed, which will of course permit the upper sash also to swing inwardly as illustrated in Figure 3, its sash cord being also removed and held as before described.

When it is desired to return the sashes to their normal functioning positions the upper sash is first swung inwardly and the lower portion of the parting stop 7 inserted in place, and upon the sash being pushed upwardly the hinge connections between the sash and the other parting stop will be broken as the pins 20 leave the female members upon the sash being pushed upwardly. The lower sash is neXt swung back into place and the lower portion 3 of the inner stop is re-positioned in place and secured by means of the thumb screw 4:- The lower sash is then pushed upwardly to a slight degree until the pins 13 of the swingable male hinge members leave the orifices 17 of the hinge members and when this is done the swingable hinge members are swung back into the former positions illustrated in Figures 1 and 5 which will permit the lower sash to be pushed downwardly to the full extent as the swingable hinge mem- 113ers will now clear the female hinge memers.

From the foregoing description it will be apparent that I have devised an extremely simple and efficient set of attachments for any standard sliding window which can be readily attached at a minimum of time and cost, and which obviate the difiiculties and hazards usually attendant upon the cleaning of sliding windows; without disfiguring the construction thereof or departing from the standard practice of the window construction.

What I claim as my invention is:

A sash supporting hinge for a window structure of the character described, comprising a female hinge member having an orifice therein and adapted to be secured to the window frame, a male hinge member comprising a substantially T-shaped plate having a slot in the transverse portion thereof; said plate adapted to be pivotally mounted in the Vicinity of its lower end upon the window sash so that it can be swung into and out of the female hinge member engaging position, a stop member adapted to extend from the sash through the slot in the plate to limit the swinging movement thereof, a downwardly extending hinge pin mounted upon one end of the transverse portion of the plate and adapted to enter the orifice in the female hinge member when such male member is swung into the engaging position.

WILLIAM JOHN BLAKE.
